Hey all,

I'm running v22.10-release of vpp from fdio repositories, on Ubuntu 22.10.
I'm experimenting with linux-cp for a control plane including GRE tunels,
and I stumbled upon an easy to reproduce crash:

unix {
  cli-listen /run/vpp/cli-vpp1.sock
  nodaemon
  coredump-size unlimited
  full-coredump
}
api-segment { prefix vpp1 }
plugins {
  plugin linux_cp_plugin.so { enable }
  plugin linux_nl_plugin.so { enable }
}
dpdk {
  socket-mem 1024
  dev 0000:00:10.0
}
linux-cp {
  #default netns dataplane
  lcp-sync
  lcp-auto-subint
}

vpp# set interface ip address TenGigabitEthernet0/10/0 10.1.2.3/24
vpp# set interface state TenGigabitEthernet0/10/0 up
vpp# create gre tunnel src 10.1.2.3 dst 10.1.2.2 gre0
vpp# lcp create gre0 host-if mytun
vpp# set interface ip address gre0 10.10.10.1/30
vpp# set interface state gre0 up

Then just `ping 10.10.10.2` from the host system.

Thanks,
Konrad Zemek
